284 SCIENCE SKETCHES. 



ally taken a trout which the Indians call No-Shee, 1 

 or Nissuee, and which must resemble the original 

 stock of the San Joaquin even more closely than 

 the Kern trout does. It has the small scales of 

 the Kern River fish, but the red cut-throat mark is 

 gone, and the spots are few and sparse. It is a 

 large trout, and is but rarely taken, the specimens 

 now known being from the McCloud. 



The common trout of the Upper Sacramento 

 may be descended from this ; but its scales are 

 larger, its body deeper, the red band on the sides 

 more distinct, and there is at least a trace of the 

 cut-throat mark, showing where its tribe came 

 from. This trout is the one distributed from 

 the hatchery at Baird as the California Rainbow 

 Trout, 2 and planted, often ineffectively, in many 

 Eastern rivers, ineffectively, I say, because of its 

 bad habit of dropping down with the current and 

 losing itself in unwholesome waters on its way to 

 the sea. The true Rainbow Trout is, however, 

 somewhat different. That name belongs to the 

 common trout of the Coast Range ; smaller, with 

 large scales, white throat, arid varying much with 

 streams and food. The large scales seem to mark 

 a change on which we make, provisionally, a divi- 

 sion of species. The little trout of the Coast 

 Range 3 is likewise an offshoot of the Steel-head. 



1 The No-Shee Trout is Salmo gairdneri stonei Jordan, named 

 for its discoverer Livingston Stone, the veteran fish-culturist of 

 the U. S. Hatchery at Baird, California. 



2 The Rainbow Trout of the Upper Sacramento is Salmo gaird- 

 neri shasta Jordan. 



8 The Trout of the Coast Range is Salmo iridens Gibbons ; the 

 type locality of the species being San Leandro Creek, in Alameda 

 County.
